The Zapara Indians in the Upper Amazon are on the verge of disappearing from the linguistic map. This is a fact. And yet, their emergence within the political landscape in Ecuador (but not yet in Peru), has provided them with a greater international visibility as an indigenous group. Most unusually, the accounts of dreams become one of the key elements of new forms of identity practices and identification processes – as those narrated here by two Zapara political leaders will attest. In search of their material and immaterial heritage, these leaders make use of the realm of dreams, using occurred dreams to orient their choices in the reconstruction of a collective memory. The dream, as a tool for engaging in a regredient process or in the return into the past, provides the historical elements that the Indians will then re-inject into their present in order to construct new “traditions”. In this dissertation, I will be describing the mechanisms, the learning of, and the local theories concerning the experience of dreams. In order to be understood, the dream must first circulate, and must have an issuer as a point of departure. Dreaming is also the means for a privileged relationship between human and non- human beings. Throughout this thesis, various systems of memory will be examined based upon empirical data revealing of the dreamt experience, but also of daily life, such as new teaching methods, or the creation of artefacts, produced both by ancestors or contemporaries. These accounts will help us to understand this new process of “Zaparaisation”, which depends as much on a process of ethno-archiving than on ethno-museography, and which awakens the immaterial.

The effect of evaporative drying on the pore size of two series of hybrid silica gels is investigated by combining beam bending on the gels and mercury porosimetry on the aerogels and xerogels with transmission electron microscopy on the xerogels. It is shown that the shrinkage of the pores during drying is different in the two series: in one series the pores shrink proportionally to their volume, in the other the pores collapse until they all reach the same size. The experimental data enable us to discuss the relation between these two different behaviours and the different morphology of the two series of gels. [less ▲]

Le secteur Open Source connaît une profonde mutation: à côté de l’idéologie libertaire prônée par ses défenseurs, il migre vers une "économie de marché" au sein de laquelle les acteurs développent désormais de réelles stratégies commerciales. A partir d’une étude exploratoire, basée sur l’analyse de six cas d’entreprises, notre recherche met en évidence les modèles d'affaires privilégiés par ces sociétés pour positionner leur offre de produits/services et générer un retour lucratif à leurs activités. Synthétisés au travers de trois approches distinctes – les logiques de la complexification, du système clos et de l’intermédiation –, ces modèles économiques reflètent des positionnements foncièrement différents par rapport à la philosophie Open Source et soulignent les ressources (au sens de Barney, 1991) que les entreprises mobilisent pour créer un lien de dépendance envers leur clientèle et se forger un avantage concurrentiel durable.

From a hybrid systems point of view, we provide a modeling framework and a trajectory tracking control design methodology for juggling systems. We present the main ideas and concepts in a one degree-of-freedom juggler, which consists of a ball bouncing on an actuated robot. We design a hybrid control strategy that, with only information of the ball’s state at impacts, controls the ball to track a reference rhythmic pattern with arbitrary precision. We extend this hybrid control strategy to the case of juggling multiple balls with different rhythmic patterns. Simulation results for juggling of one and three balls with a single actuated robot are presented. [less ▲]

This paper presents numerical and analytical investigations on iron columns under axial compression, strengthened with high modulus carbon fibre reinforced polymer (FRP) sheets. Numerical and analytical models are proposed to predict the resistance and stability load of such elements, including effects of section and member geometrical imperfections and of the nonlinear characteristic and the anisotropy in post elasticity of iron material. It is shown that axial resistance and stiffness of iron columns can be increased significantly with the use of longitudinal FRP sheets as a result of the reduction of the column slenderness, but also that transverse FRP sheets should also be used to avoid any local buckling of the longitudinal FRP sheets during loading.

It is a question of varying various technical combinations (thermo isolation, heating system, renewable energy…) equipping this dwelling in order to obtain a panel of realistic solutions to study under energy” and “economic” angle the “. The analysis of these projects must make it possible to release a maximum level of consumption in primary energy per m ² and per annum, as well as a maximum level of CO2 emission, both realistic as well from the environmental point of view as economic.

Purpose of review Patients in a vegetative or minimally conscious state continue to pose problems in terms of diagnosis, prognosis and treatment. Despite recent waves of international media attention following Terri Schiavo's death and the 'miracle recovery' of Terry Wallis, research efforts aimed at increasing our knowledge about brain function in these conditions remain scarce and must address a series of difficulties, including financial and ethical barriers. Here we review current possibilities and limitations of clinical and para-clinical assessment of chronic disorders of consciousness. Recent findings During the past year the field has witnessed publication of significant, yet isolated, case reports in top-ranking journals, including Science and Nature. Such milestone reports and other impressive recent technological advances in the study of vegetative and minimally conscious patients reveal enthralling areas of science that must find their way to clinical medical reality. Summary Consciousness is a subjective experience whose study has remained within the purview of philosophy for millennia. That has finally changed, and empirical evidence from functional neuroimaging offers a genuine glimpse at a solution to the infamous mind-body conundrum. New technological and scientific advances offer the neurological community unique ways to improve our understanding and management of vegetative and minimally conscious patients. [less ▲]
